The insert flange refers to the flange ring step at the end of the pipe, which is welded on the pipe end and outer side, available in two forms: with neck and without neck.
Features
Advantages: Easy to install, no special equipment or technology is required, just insert the pipe into the flange socket and then weld it.
High strength after welding, able to withstand high pressure and tension.
Good sealing performance, effectively preventing medium leakage by reasonably selecting the sealing surface form and gasket.
Related parameters
Pressure rating: Common pressure ratings include 1.0MPa, 1.6MPa, 2.5MPa, 4.0MPa, 6.4MPa, 10.0MPa, etc., which can be selected according to actual usage needs.
Sealing surface forms: Mainly include flat surface (RF), concave-convex surface (MFM), tongue and groove surface (TG), ring joint surface (RJ), etc. Different sealing surface forms are suitable for different media and pressure conditions.
Material selection
Carbon steel: Such as ASTM A105, 20#, Q235, 16Mn, etc., which have good strength and toughness, relatively low Price, suitable for general industrial pipeline systems.
Stainless steel: Such as ASTM A182 F304, 304L, F316, 316L, etc., which have excellent corrosion resistance and high-temperature resistance, suitable for pipeline systems in corrosive media or high-temperature environments.
Alloy steel: Such as ASTM A182 F1, F5a, F9, F11, F12, etc., which have high strength and hardness, as well as good corrosion resistance and high-temperature resistance, suitable for high-pressure, high-temperature, or highly corrosive pipeline systems.
Manufacturing standards: Mainly include ANSI B16.5, HG20619-1997, GB/T9117.1-2000—GB/T9117.4-2000, HG20597-1997, etc. Different standards may have certain differences in Size, tolerances, technical requirements, etc.
Application range: Widely used in pipeline systems in industries such as boiler pressure vessels, petroleum, chemical, shipbuilding, pharmaceuticals, metallurgy, machinery, and food, used for connecting pipes, valves, pumps, and other equipment.
